The central sustainability challenge examined in this analysis is the escalating and irregular global deployment of solar photovoltaic (PV) electricity generation between 1990 and 2024 and whether the current trajectory is sufficient to meet international decarbonisation commitments by 2030 and 2035. The variable of interest is total world solar electricity generation (Terawatt-hours, TWh), sourced from the Energy Institute’s Statistical Review of World Energy 2025 (74th edition), specifically the “Solar Generation – TWh” panel of the EI-Stats-Review-ALL-data.xlsx dataset.
